The idea behind Rob Becker's 1991 solo show is that the differences between men and women stem from caveman days. Women are gatherers of information--that's why they're always talking to their girlfriends. Men are strong, silent hunters--they flip through channels because they're killing them as they go. In this touring production, burly, bearded Chris Sullivan delivers Becker's lines affectionately if somewhat impersonally: he always seems to be performing a role, not telling fresh stories about life with his partner, Nicole. He explains that men are focused on building safe places for women to "practice their magic," which seems to consist of chatting on the phone and shopping. There are funny moments, and audience members seemed to enjoy elbowing their spouses whenever something struck them as particularly relevant. But Becker's exploration of stereotypes never gets deeper than, well, stereotypes. Open run: Wed-Fri 8 PM, Sat 5 and 8 PM, Sun 3 PM. Lakeshore Theater, 3175 N. Broadway, 773-521-2283. $39.50-$45.
